i mixed up returns, please advise.

Hi!

 

Please help. I have 3 businesses. 2 of which i was reporting $0s on and a 3rd i was reporting a profit. I mistakenly mixed up the one I was suppose to be reporting a profit with one i was suppose to be reporting a $0 and sent that. (mainly because one of the $0s was my primary business the year before.)

 

How should I approach the situation?

 

Call and ask to cancel because i sent the wrong return or what? 

 

Thank you so very much.
